The rotating fan, driven by the spring motor will direct an upward blastof air in wardly of the wall 38, the air passing through the fabric andopening 41 while the dust and dirt settles back into. the

pocket between the wall 38 and the casing;

Tl-i-re will be a comparative cahn in this pocket so that-the dust willnot be kept in illl'ilgltilted whir-lby th'e upward blast of air from-.the-fan. i i

By removing the strip 43'other devices,

' such as scraping strips, brusliesor the like can be substituted so asto adapt the devices for use'on carpets, the" upholsteryof furniture.curtains or the like. Mounted on the shaft 15, in the upper portion ofthe casing lOfis a centrifugal governor a4.

\Vlien the lerer 37 is moved toward the right in Fig. 1, the pinion 32will be turned so tli'atits pawl 36 moves idly over the ratchet wheel35, no movement being communicated to the shaft 30 by reason of the fartthat the pinion 32 is'loosely mounted on the said shaft. \Vhen the leveris moved toward the outwardly extending member 45,"

carried by the casing 10, the pinion 32 will be turned in the oppositedirection so that its pawl 36 engages with the ratchet wheel and turnsthe shaft 30. -1\Io\"'eine'iit will be communicated to the shaft 2(3tlirough the medium of. the pinion 28. Theplain portion of this pinionturns the pinion 23 and causes the \v1n .l1ng,of the motor spring 2?.The l'iltQllGt wheel 27 engages idly with the pawl 29. This backward andforward movement of the lever 37 will be continued until the motorspring is completely wound.

The pawl 29 prevents backward movementof the shaft 26 so that'the springwill not 'unwind when the lever is moved to the The unwinding of theright in Fig. 1.

spring will take place from the center, so

that the shaft 22 will be rotated carrying with it the pinion 21' anddriviii the 'shaft 18. This shaft, through the medium. of the pinion19and the pinion 16 on the shaft 15 rotates tlie"last-naniedshaft withits fan. 5

By reciprocating the lever 3.7 every once in a while during the movingof the device over the horses-body, the spring can be kept wound to sucha tension that the maximum speed can be imparted tothe fan.

One side of the dome is provided with a.

cleanoiit opening closed by a sliding door \Vhat is claimed is:

A vacuum i cleaning device comprising an outer shell having its upperportion closed and perforated, an upwardly and inwardly extending wallin the lower portion of the shell provided with an inlet opening andforming a circular pocket be-' tween the wall and the shell, air currentproducingnreansvmovable in said pocket,-a fabrie lining disposedinwardly of the perforated portion of thetshell, andfaii upwardlyandinwardly extending wall form- 'ing a circular pocket between it and saidshell for the reeeptionof the (lust drawn up
